ROAD PLANER.

Application filed August 25, 1919. Serial No. 319,596.

To all whom it may concern.

Be it known that I, ORTUS E. MoA'rs, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Road Planers, of

which the following is a specification, reference being had to the accompanying drawings.

My invention relates to road machines, and has for its object to provide road planing appliances so constructed and designed as to be capable of easy attachment to practically any standard type road grading machine frame equipped with the usual mechanisnr for raising or lowering or otherwise adjusting the scraper with which such machines are usually provided, after first removing such scraper, so that an ordinary road grader may readily be converted into a planer or leveler at slight expense, or be as easily restored to its original condition, this not only making it unnecessary for road officials to purchase complete machines for the diflerent classes of work, but also making it practicable to make use of old discarded road grading machine frames for planing work. I accomplish this object as shown in the accompanying drawings and as hereinafter described. That which I believe to be new and desire to cover by Letters Patent is set forth in the claims.

In the drawings:

Fig. 1 is a side view of an old road grader equipped with my improved road planing mechanism, the wheels on the near side of the machine being omitted for clearness of illustration.

Fig. 2 is a top or plan view of the machine shown in Fig. 1, but with the forward end portion of the machine broken away.

Fig. 3 is a fragmentary view showing a changed position of adjustable parts.

Fig. 4 is an enlarged detail, being a crosssection taken on line 44 of Fig. 2, and

Fig. 5 is a rear view of my improved machine.

Referring to the several figures of the drawings, in which corresponding parts are indicated by the same reference characters, 20 indicates the frame of a road grader of a well-known type supported by wheels 21, 22, near its forward end, the connection between the Wheels and frame being of any approved type. Near its rear end, the frame 20 is provided with supporting wheels 23 and 24 which are journalled respectively upon axle members 25 and 26, such axle members being adjustable laterally by means of hand wheels 27 fixed upon vertical shafts 28 provided with spur gears 29 which mesh with racks 30 carried by said axle members. 31 indicates a seat of any approvedtype mounted near the front end of the frame.

Coming now to'the construction and arrangement of the planing attachment and the devices by which it is applied to'the framework of a standard road machine, as best shown in Fig. 1, I provide a draft frame with which the planerbla-des are connected and which is arranged to be. attachedsubstantially as a unit to the usual operating equipment of a standard road machine after the scraper thereof has been removed. This draft frame comprises angle iron bars 32, 33 connected together near their forward ends by a plate 34, which in turn is pivotally connected by means of a pin 35 (see Fig. 1) with the usual. draft devices comprising the pole 36 and the parts associated therewith. Another plate 37. is secured to the draft bars 32 and 33 in anysuitable manner near their forward ends. The bars 32 and 33 are extended at their rear ends by means of bars 38 and 39 which are connected. together at their rear ends by means of a cross-plate 40.

Extending forward from the middle .part of the said cross-plate 40 (see Fig. 2) is a short plate 41 the forward end of which is piv-' otally connected by means of a pin 42 with the lower end of a link 43. The upper end of the link 43 (see Fig. 1) is pivotally connected by means of a pin 44 with a bellcrank lever 45, which with its sector 46 is suitably mounted upon the rear end of the frame 20, being removably secured in such position by means of plate (see Fig. 5). Each of the planing blades employed (see Figs. 2 and 4) comprises a longchannel bar 47 having bolted along one side a share 48, in the construction shown the share being made in two parts. As will be seen by an inspection of Fig. 4, the opposite edges of the share 48 are of similar form whereby the share is adapted to be reversed in position upon the channel bar so as to utilize both edges alternatively in operation. At its forward end portion the planing blade is provided with a weight-plate 49 which assists in procuring proper operative contact between the share and the surface of the ground. The planing devices, as applied to the machine illustrated, are indicated as a whole by reference characters 50 and 51 respectively. Each of the planing devices 50 and 51 is provided at its rear end with a yoke 52, such yokes being pivotally connected to the ends of the cross-plate 40, as is best shown in Fig. 5. As may be readily understood, by a movement of the lever 45 to the left as viewed in Fig. 5, the link 43 is moved upwardly, carrying with it the plate 41, the cross-plate and the rear end portions of the planing blades 50 and 51. It will be understood that by an adjustment of the lever the pressure of the planing devices upon the ground may be varied as may be desired, or the rear end portions of the planing devices may be lifted entirely free from contact with the ground.

Near their forward ends, the planing blades and 51 are provided with brackets 53 by which pivotal connection is effected between the planing blades and laterallyextending bars 54, such bars 54 being provided at their outer ends with vertical pivot pins 55 for this purpose. As is best shown in Fig. 2, the inner ends of the bars 54 are slidably mounted upon the laterally-extending arms 56 of a cross-frame fixedly mounted upon the draft bars 32 and 33, such crossframe comprising also a laterally-extending brace bar 57 which connects the ends of the arms 56. The slide-bars 54 are free to move inwardly along the arms 56, but are limited in their outward movement by the brace bar 57. As is shown in Fig. 3, a pin 58 may be placed in any one of the holes 59 in the arms 56 for further limiting the outward movement of the bars 54 and the planing blades 50' and 51 connected with such bars.

Adjustable means is provided upon the old type of road machine frame employed which furnishes an adjustment in addition to that afforded by the arms 56 for controlling the position of the forward end portions of the planing blades 50 and 51. This adjustable means comprises chains 60 which are secured to the forward end portions of the brackets 53 when the attachment is applied to the old frame, such chains beingconnected at their upper ends to rack-bars 61 which engage spur gears 62 mounted inbrackets 63 carried by the upper ends of standards 64 rising from the frame 20. As is shown in Fig. 2, the upper ends of the standards 64 are connected together by a cross-bar 65 which serves very materially to relieve the lateral stress upon such standards. The gears 62 are connected by means of universal joints 66 with shafts 67, the rear ends of which are journalled upon brackets 68 carried at the upper ends of standards 69. The

shafts 67 are connected by means of bevel gears 70 and 71 with transversely-extending shafts 72 which are also journalled in the brackets 68 and which are provided upon their inner ends with hand-wheels 73. By rotation of the hand-wheels 73 in counterclockwise direction as seen in Fig. 1, motion is transmitted to the gears 62 in the direction for causing an upward. movement of the rack-bars 61, thus serving to shorten the ef fective length of the connections between the planing devices and frame of the vehicle. This serves to exert a pull upwardly and inwardly upon the forward end portion of the planing device, whereby the pressure of the 8 0 planing blade upon the ground may be varied. If desired, these connections may be so shortened as to lift the planing device out of contact with the ground, as is desired for transportation of the machine.

As will be readily understood, when the vehicle is drawn forward with the planing blades resting upon the ground as shown in Fig. 2, a quantity of dirt is displaced inwardly by the planing blades, the cutting down of the high places by the planing blades and the filling of the low places by the displaced dirt serving to level the road and at the same time to produce a crown along the middle of the road. For properly spreading and distributing the dirt which is piled up in the center by the action of the planing devices, I have provided a spreader 74 pivotally mounted upon the cross-plate 40 by means'of a pivot pin 75. For 0011- trolling the position of this spreader, I have provided a link 7 6 pivot-ally connected at its lower end to the spreader 74 and pivotally connected at its upper end to a bellcrank lever 77 pivotally mounted upon a bracket 78 extending rearwardly from the link 43. A locking sector 79 is provided upon the bracket 7 8 for co-operation with the lever 77. By means of the lever 77 .the spreader 74 can be adjusted to any desired height with respect to the planing devices for effective operation under varying conditions. I

For assisting in holding the planing de vices 50 and 51 in proper position laterally, I have provided flexible connections 80 and 81 connecting the rear end portions of the frame 20 with the draft bars 32 and 33 as is best shown in Fig. 2.

Practically all grading machines of standard types are substantially alike in that they comprise a main frame mounted on front steering wheels and rear wheels carried by extensible axle members, together with mechanism mounted on the main frame for raising or lowering and otherwise adjusting a scraper blade disposed intermediately under the main frame and connected with the draft devices, and the general construction of these parts in most standard machines is much the same as that illustrated in the drawings, which may be regarded as typical. It will be apparent from the foregoing description therefore that the attachment of my improved planing equipment to such a machine is a very simple matter as it involves merely the removal of the usual scraper and connecting the planing attachment to the appropriate parts of the original machine. This can be done in a comparatively short time, and can as easily be undone, so that with an equipment consisting of a standard road grader and my im proved planing attachments practically the benefit of two machines is obtained at little more than the cost of one. Furthermore, old grading machines which have outlived their usefulness for strenuous work can well be employed in connection with my attachments for the lighter work of planing or leveling.

So far as I am aware no one has heretofore proposed to provide an attachment of the character and for the purpose described and the claims hereinafter made are therefore to be construed accordingly.

By my construction comprising the draft bars 32 and 33 rigidly connected together at their forward ends and connected by the cross-plate 40 at their rear ends, I have provided in effect a triangular draft frame, the cross-frame comprising the arms 56 and the brace bar 57, in co-operation with the slide bars 54, serving with the triangular draft frame to apply the draft very effectively from the draft means at the forward end of the vehicle to the planing blades.
